So, a normal adult human has 206 bones.
Did you know that half of these 206 bones are present in the hands and feet?
The skeletal system is one of the important human body systems. Given above were some interesting facts above the human skeletal system.
Now, let us study it in detail.
The skeletal system is one of the important human body systems.
I have divided the human skeletal system, into 4 sections for better understanding, so let us go from top to bottom and study the human skeleton.
Bone Structure of the Head
Bone Structure of the Chest and Hip
Bone Structure of the Hand
Bone Structure of the Leg
It can be a bit difficult to remember all the scientific names of bones, but here is my secret technique of remembering the names.
- First, divide the labeled diagram of skeleton in 4 sections, like above, which are head, arms, chest + hips and the fourth one - legs.
- So, for the head remember J, F and C, which are for Jaw bones, Facial bones and Cranium.
- For legs remember the letters F, P, T, F, T and M and memorize the order, these letters stand for Femur, Patella, Tibia, Fibula, Tarsals and Metatarsals.
- In a similar manner use the method, for chest + hips section and hands section.
For practice, you can print the blank skeleton diagram illustrated below.
Given above were the tips on memorizing the various parts of the skeleton. Here are some interesting facts about skeleton.
Among the 206 bone in the human skeletal system, 52 are found in our feet!
Bones are made of hard stuff which makes them strong, however, bones also have many living cells that help in their growth and repair.
Did you know that the smallest bone in the human body is located in the ear? The size of the smallest bone called stirrup, is the size of a grain of rice.
Bones are filled with bone marrow, which is a fatty substance.
To keep the bones strong, one should exercise regularly.
In adults, the bones contribute to 14% of the total body weight.
Did you know that one person out of 20 has an extra rib? Strange, right?!
The cartilage disintegrates faster than the bone, hence you will observe absence of nose or ears in the skeleton.
Also, babies don't have kneecaps. Technically, they do have kneecaps but they are soft cartilage and yet to harden into bones.
Giraffes and humans both have 7 bones in their neck, however the vertebrae present in the giraffe's neck are way longer!
Bones are stronger than concrete and steel, still doctors can be seen fixing fractures year-round!

There is a little difference between the male and female skeleton, but mostly they look similar. The female skeleton is slightly smaller and less robust. The female skeleton also has a wider pelvis, compared to the male skeletal system. So study the above diagram, and for memorizing, draw it a few times and keep labeling!
